Moving a snap between channels helps to manage a user’s expectations in any trade-off between stability in the stable channel, and cutting edge features in the edge channel (as an arbitrary example). But its also a useful technique for beta testing, or for when a snap needs to revert to a previous revision.
See Releasing your app for details on how to upload and publish a snap if you haven’t done so already.
The web UI’s release management functionality is equivalent to using
snapcraft release on the command line, and both require that you first login to the store.
After logging in to the Snap Store and selecting a published snap, click the ‘Releases’ tab to access the release management functions.
The Releases page lists which revisions of a published snap will be delivered to users tracking a specific channel.
On the command line, with a developer account already created, enter the following to login:
$ snapcraft login
The command line equivalent to the web UI’s Releases page is the output from
snapcraft status <snap-name>:
snapcraft status grv Track Arch Channel Version Revision latest amd64 stable 0.3.2-3-g0a5a940 12 candidate 0.3.2-3-g0a5a940 12 beta 0.3.2-5-gcffa246 13 edge 0.3.2-5-gcffa246 14
To move a snap between channels in the web UI, simply drag a revision from one channel to another, or use the cog drop-down menu on a revision and select a destination. Click Apply to make the requested change.
On the command line, the release command takes the snap name, the revision you wish to move and the destination channel (or channels) as its arguments:
$ snapcraft release mysnap 13 candidate
You can also move earlier revisions back into a channel:
$ snapcraft release mysnap 5 beta
See Channels for more details on how channels, tracks and branches can be used.
